The Dragon's Guardian

An orphan abandoned in a mysterious forest. And... Freya, who can see other people's emotions as colors.
Positive emotions are golden. Negative emotions are black.
Her mysterious ability was a secret she kept to herself.
On her pilgrimage to become a priestess, Freya woke up in a stranger's bed.
"You... what are you?"
The man, Aran, asked threateningly, his red eyes glowing. He looked exactly like the hero from the mural Freya had seen since she was young, even sharing the same name.
At first, she thought it was a dream. She believed she was just having strange dreams.
But somehow... It doesn’t seem like a dream.
Who is this man? Where do I go every night? Why is it 'me'?
